Re: Steeper current adjustment?

I just received the 3 axis stepper driver and it appears there is no current adjustment for the steppers. Does it have the ability to adjust current on the board? Formula: Vref/5Rs Vrf = Voltage at pin#10 Rs= the current resistor (the bigger one you seem on the board, usually 2Watt) Example: 1.0ohm...

Re: 2 remotes

I think you have to have both remotes on the same digital code. The instructions should tell you how to do this. I probably involves soldering. Of course they need to match the frequency of the reciever as well (this you cannot change). There are about 3 different model out there even with the same...
